Has anyone ever used DARK MULE v0.2.pk3 to customize their skins?
I tried everything I can’t launch this pk3 whether on my server or just with WET

I need more details, what mod is your server running,
the skin also needs some server settings
This package requires modification +set com_hunkmegs 128
How to do this???
-The easiest way is... drop down the console ~ in Wolfenstein ET main
screen, then type the following command:
/set com_hunkmegs 128
then restart the game

-Here's another way... right-click on the Enemy Territory desktop icon
then go on the properties, then see Targen line. One the end of Tardet
line add the following command +set com_hunkmegs 128... for example...

"C:\Program Files\Wolfenstein - Enemy Territory\ET.exe" +set com_hunkmegs 128

2.Before you install z_dark_mule.pk3, you should delete any
additional non-standard skin or sound packages from ETmain folder
or from folder of your prefered mod (jay_mod, ETpro_mod etc...)
